The investigation was led by Michael Chazan of the University of Toronto. The team located burned bones and ash plant material that included grasses, leaves and twigs. The bones were from animals ranging from small rodents to horselike mammals.

There was no evidence that the materials found were burned outside then brought into the cave or that a wildfire might have spread from the area surrounding the cave."Link to Original Source
